[0052] First embodiment

[0053] like Figures 1 to 4 As shown, the first embodiment of the present invention provides a child safety seat 10 , including a seat body 100 , a seat belt 200 , a first blocking member 300 , a limiting member 510 , a second blocking member 600 and a clamping member 700 .

[0054] Specifically, Figure 1 As shown, the seat body 100 includes a base 120 and a backrest 130 connected to each other to form a seating space 110. A child sits in the seating space 110. The base 120 is used to support the child's buttocks, and the backrest 130 is used to support the child's back. In this embodiment, the base 120 and the backrest 130 are made of plastic material, but the present invention is not limited thereto.

[0055] like Figure 1 and Figure 2As shown, the seat belt 200 has a first connecting section 210, a second connecting section 220 and a third connecting section 230. The first connecting section 210 has a first end 211 and a second end 212, the first end 211 is arranged on the back of the backrest 130, and the second end 212 goes around the back and the front of the backrest 130 to fix the child in the seating space 110. In this embodiment, the child safety seat 10 further includes a first connecting member 410 and a second connecting member 420. The first connecting member 410 is located on the back of the backrest 130, and the second connecting member 420 is located in the seating space 110. The first connecting section 210 includes a first shoulder strap 201 and a second shoulder strap 202 arranged in parallel, the first end 211 of the first shoulder strap 201 and the first end 211 of the second shoulder strap 202 are both fixed to the first connecting member 410, the second end 212 of the first shoulder strap 201 and the second end 212 of the second shoulder strap 202 bypass the back of the backrest 130 to enter the seating space 110, and then are both connected to the second connecting member 420. In this way, the first shoulder strap 201 and the second shoulder strap 202 respectively fix the shoulders of the child to the child safety seat 10. The second connecting section 220 has a third end (not shown in the drawings) and a fourth end 222, the third end is arranged on the front of the base 120, and the fourth end 222 bypasses the front and back of the base 120 to connect to the second connecting member 420 with the first ends 211 of the two shoulder straps. The third connecting section 230 has a fifth end 231 and a sixth end 232. The fifth end 231 is connected to the second connecting member 420. The sixth end 232 is connected to a buckle (such as a Japanese buckle) and is arranged inside the base 120. In this way, the seat belt 200 can fix the child in the seating space 110 on the child safety seat 10. In this embodiment, the first connecting member 410 is, for example, a five-point safety buckle and the second connecting member 420 is, for example, a metal webbing buckle. Of course, in other embodiments, the first connecting member 410 and the second connecting member 420 may also be in other forms. Moreover, in other embodiments, the seat belt 200 may also be arranged in other ways.

[0056] It should be understood that the "front" and "back" described herein are specifically referenced to the seating space 110. For example, the front of the backrest 130 refers to the side of the backrest 130 facing the seating space 110, the back of the backrest 130 refers to the side of the backrest 130 facing away from the seating space 110, and so on.

[0057] like Figures 2 to 4As shown, the first blocking member 300 is fixed to the back of the base 120. Specifically, the base 120 is provided with a long strip accommodating portion 121, and the first blocking member 300 is installed in the accommodating portion 121 by fasteners such as screws. The seat belt 200 is against the first blocking member 300, and the first blocking member 300 is used to prevent the base 120 from deforming. In this way, when the car is hit or braked suddenly, the seat belt 200 is pulled and pulled by the impact force, causing the base 120 to deform, resulting in the length of the seat belt 200 in the riding space 110 being lengthened, so that the degree of upward displacement of the child's head is too large, and the damage to the child's body is effectively reduced. Of course, in other embodiments, the first blocking member 300 can also be fixed to the back of the backrest 130, and the seat belt 200 is against the first blocking member 300, and the first blocking member 300 is used to prevent the backrest 130 from deforming.

[0058] Furthermore, the first blocking member 300 may protrude from the back of the base 120 so that the seat belt 200 is spaced apart from the back of the base 120. In this way, the seat belt 200 is not in direct contact with the base 120, but is in direct contact with the first blocking member 300. When the car encounters an unexpected situation such as a collision or sudden braking, the first blocking member 300 can withstand the impact force of the seat belt 200, thereby protecting the base 120 from being deformed by the seat belt 200, preventing the length of the portion of the seat belt 200 located in the seating space 110 from becoming longer, thereby reducing the degree of upward displacement of the child's head.

[0059] Furthermore, the hardness of the first blocking member 300 is greater than the hardness of the base 120. Thus, the first blocking member 300 is disposed on the base 120, which can increase the structural strength of the base 120. When the car encounters an accident such as a collision or sudden braking, the base 120 is not easily deformed by the pulling and dragging of the seat belt 200, and the length of the portion of the seat belt 200 located in the seating space 110 can be prevented from becoming longer, thereby reducing the degree of upward displacement of the child's head.

[0060] Optionally, the first blocking member 300 is rod-shaped and is embedded or partially embedded in the back of the base 120. In this embodiment, the first blocking member 300 is partially embedded in the back of the base 120, so that the seat belt 200 directly abuts against the first blocking member 300, and the seat belt 200 is spaced apart from the back of the base 120.

[0061] Furthermore, if Figure 2As shown, the stopper 510 is used to limit and fix the seat belt 200 to the back of the backrest 130. In this way, the length of the portion of the seat belt 200 located in the passenger space 110 can be further limited to prevent the portion of the seat belt 200 in the passenger space 110 from being pulled and lengthened when the car encounters an accident such as a collision or sudden braking, thereby reducing the degree of upward displacement of the child's head.

[0062] Furthermore, in one embodiment, at least one stopper 510 may be disposed on the first stopper 300 and the second stopper 600. Figure 2 and Fig.10 As shown, the child safety seat 10 further includes a fixing rod 520 (which can be selected and set according to actual needs), the fixing rod 520 is fixed to the back side of the backrest 130 , and the limiting member 510 is pivotally connected to the fixing rod 520 .

[0063] The limiting member 510 has a limiting portion 511, and the limiting member 510 can rotate in a direction close to the backrest 130 so that the limiting portion 511 presses the seat belt 200 against the back of the backrest 130. In this way, the limiting member 510 can be rotated in a direction close to the backrest 130 to press the seat belt 200 against the back of the backrest 130 through the limiting portion 511, so as to prevent the portion of the seat belt 200 located in the seating space 110 from becoming longer when an accident occurs, thereby reducing the degree of upward displacement of the child's head. In this embodiment, the limiting portion 511 includes a plurality of limiting teeth 511a. When the limiting member 510 rotates in a direction close to the backrest 130, the limiting teeth 511a press the seat belt 200 against the back of the backrest 130, and a large friction force can be generated between the limiting teeth 511a and the seat belt 200, thereby producing a better limiting effect. When it is necessary to adjust the length of the portion of the seat belt 200 located in the seating space 110 according to the size of the child in the seating space 110 , the limiting member 510 can be rotated in a direction away from the backrest 130 to release the abutment of the limiting portion 511 on the seat belt 200 , thereby facilitating adjustment of the length of the portion of the seat belt 200 located in the seating space 110 .

[0064] In this embodiment, Figure 2 and Fig.10 As shown, the limiting member 510 includes a limiting body 512 having a substantially U-shaped structure and a limiting portion 511 fixed to the middle of the limiting body 512. Both ends of the limiting body 512 form a pivoting portion 512a to pivot with the first blocking member 300 or the fixing rod 520. Of course, in other embodiments, the limiting member 510 may also be in other forms.

[0065] Furthermore, if Figure 1 and Figure 2As shown, the backrest 130 has a through hole 131, and the second end 220 of the seat belt 200 is passed through the through hole 131 from the back of the backrest 130 to the front of the backrest 130, that is, enters the seating space 110, and the fixing rod 520 is arranged opposite to the through hole 131. In this way, the seat belt 200 can be better limited and fixed. In this embodiment, there are two through holes 131, and they are arranged at intervals along the lateral direction of the backrest 130 to allow the first shoulder belt 201 and the second shoulder belt 202 to pass through respectively. Correspondingly, there are also two limiters 510 to respectively press the first shoulder belt 201 and the second shoulder belt 202 against the back of the backrest 130.

[0066] Furthermore, if Figure 1 and Figure 2 As shown, the car has a vehicle safety belt 20, and the vehicle safety belt 20 is used to pass through the front of the backrest 130 to fix the child safety seat 10 on the car. The second blocking member 600 is fixed to the backrest 130 and is used to prevent the backrest 130 from being deformed. The child safety seat 10 is fixed to the car through the vehicle safety belt 20, and the second blocking member 600 fixed to the backrest 130 can prevent the backrest 130 from being deformed, thereby preventing the backrest 130 from being deformed (for example, the lateral dimension becomes smaller) under the pulling action of the vehicle safety belt 20 when the car encounters an accident such as a collision or sudden braking, which causes the vehicle safety belt 20 to become loose relative to the child safety seat 10, thereby preventing the child safety seat 10 from being displaced and reducing the degree of upward displacement of the child's head.

[0067] Furthermore, if Figure 1 and Figure 2 As shown, the vehicle safety belt 20 is used to pass through the front of the backrest 130 horizontally, and the second blocking member 600 is horizontally arranged on the back of the backrest 130. The specific installation method of the second blocking member 600 can be that the first mounting rib 132 and the second mounting rib 133 are arranged at intervals in the horizontal direction on the back of the backrest 130, and the two ends of the second blocking member 600 are respectively fixed on the first mounting rib 132 and the second mounting rib 133. In this way, the second blocking member 600 can prevent the backrest 130 from deforming and prevent the vehicle safety belt 20 from becoming loose. Of course, the second blocking member 600 can also be fixed to the back of the backrest 130 in other ways, for example, the second blocking member 600 can be embedded or partially embedded in the back of the backrest 130.

[0068] In this embodiment, Figure 2 and Fig.11As shown, the second blocking member 600 is preferably a circular tube structure, which has a simple structure and is easy to manufacture. Optionally, the outer diameter of the circular tube structure is 12 mm to 13 mm, and the thickness of the circular tube structure is 1 mm to 1.6 mm. In this embodiment, the outer diameter of the circular tube structure is 12.7 mm, and the thickness of the circular tube structure is 1.5 mm. However, it is not limited to a circular tube, and the second blocking member 600 can also be a square tube.

[0069] Furthermore, if Figure 1 As shown, the clamping member 700 is disposed on the front side of the backrest 130, and the clamping member 700 is used to clamp and fix the vehicle safety belt 20. In this way, the limiting and fixing effect of the clamping member 700 on the vehicle safety belt 20 can be enhanced.

[0070] Second embodiment

[0071] The second embodiment of the present invention provides a child safety seat 10, comprising a seat body 100, a second blocking member 600 and a clamping member 700. Figures 5 to 7 As shown, the structure of the child safety seat described in the second embodiment is substantially the same as that of the child safety seat described in the first embodiment, except that the child safety seat described in the second embodiment omits the seat belt 200 , the first blocking member 300 , the limiting member 510 and the fixing rod 520 .

[0072] Third embodiment

[0073] The third embodiment of the present invention provides a child safety seat 10, comprising a seat body 100, a seat belt 200, a stopper 510 and a fixing rod 520. Figure 1 , Figure 2 and Figures 8 to 10 As shown, the structure of the child safety seat described in the third embodiment is substantially the same as that of the child safety seat described in the first embodiment, and the only difference is that the child safety seat described in the third embodiment omits the first blocking member 300 , the second blocking member 600 and the clamping member 700 .

[0074] Fourth embodiment

[0075] The fourth embodiment of the present invention provides a child safety seat 10, comprising a seat body 100, a seat belt 200, a first blocking member 300, a second blocking member 600 and a clamping member 700. Figure 1 and Fig.12 As shown, the structure of the child safety seat described in the fourth embodiment is substantially the same as that of the child safety seat described in the first embodiment, and the only difference is that the child safety seat described in the fourth embodiment omits the limiting member 510 and the fixing rod 520 .

[0076] The above-mentioned child safety seat 10 has at least the following technical effects:

[0077] In the above-mentioned child safety seat 10, the seat belt 200 is wound around the front and back of the seat body 100 to fix the child in the seating space 110. At the same time, a first blocking member 300 is provided on the back of the seat body 100. The seat belt 200 abuts against the first blocking member 300, and the first blocking member 300 can prevent the seat body 100 from deforming. In this way, when the car is hit or braked suddenly, the seat body 100 is prevented from being pulled and pulled by the impact force of the seat belt 200, causing the seat body 100 to deform. As a result, the length of the seat belt 200 in the seating space 110 becomes longer, causing the child's head to be displaced upward to a large extent, effectively reducing the damage to the child's body.

[0078] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
